To all whom imag-concern.'

Beit-known that I, ORRIN H. GooDnIon, a citizen of the United States, and resident of Castleton Corners, Staten Island, county of Richmond', and State of New York, have made anew and useful invention in- Appliancesfor Use with Telephone-Transmitters,

of which lthe ollowingis a speciiication.

My invention is directed lparticularly to an im rovement upon appliances for enabling t sation with other subscribers inl such manner that other ersons in the same room where portion of the conversation, and it h'as for its objects, first, to provide means for'detach-- ably whollyinclosing well known forms of portable or desk telephones and in such man-'- neril that the receiver may-be utilized'in a we changes, said inclosing means being provided with a transmission opening in front of the transmitter. Second, to provide aportable or desk telephone with an inclosing casing or box having a transmission opening infront of the. transmitter so constructed as to enable thc user to effect-secret conversation with a subscriber, and to further provide means eX- terior to such casing and yieldingly connected with the usual switching lever of the telephone in such manner tha-t the receiver may ythe user.

e hung outside'of the casing and effect the -us ual circuit changes on removal and replacement. Third.,` to provide a portable or desk telephone with aportable inclosing casing or box adapted to wholly inclose the transmitter and its switching attachments, and provided withl means exterior to the casing and yieldingly connected with said switching attachments, said casing being additionally provided with a transmission opening in front ofthe transmitter and an infiatable yielding ring having such a conto-ur as to accurately tit around the mouth and nose of Fourth, to provide a portable or desk telephone with an inclosing casing or box having a transmission opening in front of the transmitter so constructed as to admit of secret conversation, and prnvided-with 'means for locking the opening closed so as to thereby prevent-unauthorized persons from using the instrument,` and also for protecting the instrument from dirt, dust and moisture.

Fifth, to provide a portable or' desk telee users of telephones to hold converwill not hear 'anyl own way foi` effecting the usualcircuit.

' My invention Will'be phone with aninclosing casing and interconnecting means between the yinclosed teleunauthorized persons-'may not use the instrument. Sixth, to provide aportable 'or desk telephonel with an inclosing casing or lbox having a' 4transmission -openinginone'side so constructed as to enable. the user to talk confidentially to other subscribers,said casi Aing .being rovi'ded' additionally with a sound absor ing or dead'ening lining, vand interconnections betweenthe usual. receiver sustaining hook` and 'a hook outside the-casing, changes of on removing and replacing the receiver with relation'to the outside hook.

whereby the circuit similar sustaining 4 the instrument may be effected f `r fully understood by Y referring to the accompanying drawings, in

a i l ,carnose- Prior to my invention appliancesfor maintaining secrecy'in telephone conversation, by covering up or surrounding the mouth and nose of the user, have been devised in which a transmitter vwas inolosed inra casing or box having an opening at one side thereo and lol cated directly in front of the transmitter, v said opening having a roper contour to admitof the insertion of t e nose and mouth of the user in such manner as to enable his faceto eifectually close the opening so that none of the sound vibrations might reach other persons in the room where the transmitter was located. Attachments have' also been devised adapted to be detaohably secured directly to the transmitter, said attachments being of such conformation as'to wholly surround the mouth and nose of the user, the

f in such lmanner as to effect secret conversalportable or desk tele tion, said hood being detachable from the transmitter of a desk telephone.

My improvement is desivned especially for use in connection with Weill known forms of hones and is so ccnstructed and arrange as to enable the user of such tele tect them'L om the' evil e .'ects of dirt, dust, and moisture, and also to'enable him tohave the exclusive use of such instrument, th ercby preventing any possibilit-y of over-charge for conversations not actually held by .him or some authorized person. y

Referring now to the drawings in detail for a full and clear understanding of the invention, such as will enable others skilled in the art to construct and usethe saine, i rep` resents the standard oi a -well known portable or desk telepb lone provided with. a transmitter 2 hinged to the upper portion of the standard, 3 being the receiver of well 1Known form and 4 the usual soring pressed' circuit changinglever provided with forks 5 and 6 for supporting t ie receiver, 37 and 38 constituting the'well known insulated conductors ofsuch. an outiit Receiving and transmit-` ting'outiits of this general structure arel and have been for years in well knownpublic use throughout the United States.

My improvementembodies a surrounding casing or box 7 provided witha transmission opening 5s at one side'having preferably the conformation of that ortion ofthe human face embracing an out ine around the nose,

`mouth and claim-said opening "being sololcated in such relation to the transmitter@ as will be hereinafter described, as to@ ive the best effects. This casing 7 1s porta le and hones to'wholl surround or pron made preferably of wood and .is lined throughout interiorly, except atthe botton'rr7 with a goed sound absorbing medium 9, preferably thicir felt or the like lnside of this lining isa second'lining l0 of thin soft rubber sheeting material, `as fe t.

transmission 0 ening 8 and constituting a seat for a meta clamping ring 13, the function of which Will be described later on.v

i4 is a removablebase adapted to whoil inclose the lower end of the box when the te ephone is in place, the inner portion of said base being inclined in the manner shown in Fig. 4 and provided with a soft sound absorbor` other licht material, and inside of thisA 'is still a third ininv 11 of good sou-ndabsorb- 12 is a wooden ring secured around'the.l i

ing medium l5 of felt or tl'ieiltgeifor support.-

ing the base of the telephone proper; 16 being a ring adapted to rigidly. secure said base in' place` as shown in Fig. 4. Openings are rovided as shown inAFig. 4 at the rear and ottom of the casing for the passage ofthe usual conductors 37, 38 of such an outiit. The base 141 is inclined in the manner shown for the purpose of economizing space and enlabling the instrument to be located in the best l possible position for use at ordinary desk or table levels'.

17 is. arforlrcd standard or support at the back of the casing for gripping or rigidly holding the upper end of the standard, the arrangement being such that when the telephone is secured in the manner shown it is entirely stable and it and itsinclosing casing 7 are jointly portable and may be transported from place to place and connected with any outiying subscriber. By the ex ression portable or desk telephone use in the specification and claims, l wish to be understood as meaning a telephone set embracing a. transmitter, receiver and switchinU appliance operatively connected with flexi le con-l ductors and adapted all to be sustained by a .single standard and base and to be moved from place to place in a.iooin, dependent upon the iength of theexible conductors which interconnect vthe ta hing and call circuits. ()r, the tele hone itself may be l wholl removed by withdrawing tliebase 14, said ase-l being secured by any preferredV means, such as screws, nails or the like; or, it might be provided with one or-more padlooks 'if desired.

34 is a viiexi-ble tube or ring preferably 'soft rubber provided exteriorly 4with a flange 18, the .function of which is to secure said tube or ring against the wooden: ring 12 through the agency of a metal clamping ring 13 provided with clamping screws, not shown, the arrangement being such that the ring may bedetached and washed `or otherwisecleansed, or disinfected,

35 isa filling tubewhieh maybe provided with'anyl type of valve forfretainingwhe air within the tube 34, the structure being such that said tube may be inflated to any desired extent.

19 is a slot located in one side of the sur rounding casing 7 and 2O is a metal guiding strip having a guiding slot, said strip being secured directly to the outer face of the casing by screws as shown in Fig.l2.

21 1s. a circuit changing arm provided with forks 33, 33, similar to the forks 5 and 6 of the circuit changing lever 4, the function of the saine being to sustain the telephone receiver 3 in the same manner as the like art of the instrument is secured bythe forks 5 and 6 in ordinary use, said parts constituting the'- receiver supporting hook. This cireuit c hanging arm 21 is provided with a cylindricalextension 22 having the diameter of the slot 19 and is securcd'by a screw, rivet or'otherwise directly to a vertical sliding yoke 23,-the uper end of which is sustained directly by a caf spring 24 at the top of the casing, 25 being a soft rubber .oieother yielding means for closin,r the opening through which the inner arm o the yoke 23 extends when the telephone is removed from the arm 21, thereby preventing the sound Waves from passing out through said opening. f

.To the lower end of the innerportion of the yoke 23 is adjustably secured, by a screw 27, an extension 26. The lower end of this extension is enlarged and is providedwith an inclined pin 29 adapted to bepassed through the eyes of the forks 5 and 6 of the circuit changing lever 4, the arrangement being such that Whenthe receiver 3 is suse pended by the fork 33 the weight thereof will transmit motion through the sliding yoke 23, extension 26, pin 29, forks 5 and 6 of the circuit changing lever 4and cut the call bell in and the transmitter yout of circuit, and when removed therefrom the action of the spring behind the' lower end of the lever 4, combined with the retractile force of the s ring 24, will eiiect the usual reverse circuit c anges and cut in the receiver 3, it being obvious on `ins ection of the drawings, and articularly of igs. 3 and 5,that by virtueo the circuit changing meansV described one is enabled to utilize the exterior fork 33 for'efecting the circuit changes in identically the same manner-as said circuit changes are ordinarily eiiected by removing and replacing the receiver 3 upon forks .5 and 6 and in a manner -well understood by those who usetelephones of this nature.

30 represents a slotted yielding metal strip secured at its upper end directly to the circuit changing arm 21 and 31 represents a` tical.,

' Obviously the telephone instrument asa` inner switch :lever 4, might rectly to the inner face of the rear wall of the into the position shown in 'full lines, Fi 2,

and in dotted lines Fig. 3, thereby loc ing the 'circuit' changin parts so that when the receiver is remove no conversation can be hadr -As a further safe-guardv against conversaj tion by unauthorized persons and as `a means of protecting the transmitting instrument and interconnected parts from dust, dirt, and moisture, I provide a removable door or cover 40 shown in dotted Alines Fig. '1, the same having slots at its opposite corners, sta-1 ples being securedto the casing so that when effecting the various o jects for which it-isv designed. Nor do I limit all of the details to luse especially with portable telephones, as

various modiiied forms of appliances might be devised for effecting the results accomplished, and some-of the details might be i utilized with telephones of the stationary ty conversations, and' t e entire arrangement such that the controlling-switch may. be actuated on hanging up or removing the receiver therefrom, and my claims are elleric as to these features, and various modi fed'are rangements may. be devised andv stilifeome within .the terms of my most. generic claims. To illustrate, the exterior hook and interconnecting mechanism extending into the casing. or box may be done away with entirely and the tele hone located as shown in the drawings, an .the receiver may be inserted into the casing or box through thetransmission opening and hung upon the inner switch 4 on the forks', 6, the receiver conductors 37 being located at the lower end of the.transmission opening' when it, the receiver, is on the outside; or, a groovemay be rovided at the lower edge of the opening or such conductors, it being obvious that such anarrangement would be entirely pracwhole, with thereceiver 3'sus ended o n the e secured dib'ox` and said wall hinged at one side of the pe. 95 l belleve 1t is broadly new with me to mproximate center oi the transmission opening. In this event the bottom would of course be permanently secured in place and lined inn teriorly with a sound absorbing medium'like an described.
